Gain new insights and ideas as you learn how exploration of models of environmental systems can yield insight into hazards and solutions during this hour-long online presentation.

Models of environmental systems are infinitely explorable. In addition to yielding insight into hazards and solutions, exploration can also reveal ways in which the model provides an inadequate representation of the system. Lessons addressed in this Webinar include three from Superstorm Sandy, including the power of:

Being transparent

Demonstrably improving prediction accuracy

Understanding how complex environmental systems work through data, conceptualization, and testing hypotheses by analyzing alternative models using data, sensitivity analysis, and uncertainty quantification.

It is suggested that problems of heterogeneity, inaccessibility, scale, and nonuniqueness typical of groundwater system models can be addressed using the lessons learned from Superstorm Sandy, along with the maturing ability of the groundwater modeling community to integrate data and models using inverse methods, and some new capabilities such as:

The new software capability MODPATH_OBS, which makes it easier to test models against some kinds of transport, water quality, and age data

Sensitivity graphs stacked to show the contribution of defined observation types

The importance of a modular model structure to support consideration of alternative models (demonstrated here using the FUSE surface water model and the MODFLOW groundwater model)

The new Distributed Evaluation of Local Sensitivity Analysis (DELSA) method

Students and professional researchers who develop and/or use groundwater models.
